要約
(EN)

Provided is a binder composition for a non-aqueous secondary battery electrode capable of forming an electrode for a non-aqueous secondary battery that can cause a non-aqueous secondary battery to display excellent low-temperature cycle characteristics and low-temperature output characteristics. The binder composition for a non-aqueous secondary battery electrode contains a polymer and a solvent. The polymer is a block copolymer including an aromatic vinyl monomer unit and an aliphatic conjugated diene monomer unit having a carbon number of 5 or more. The amount of the polymer that elutes into electrolyte solution is not less than 1 mass % and not more than 20 mass %.
